Description
- This application claims the benefits of priorities based on Korean Patent Application No. 10-2015-0124174, filed on Sep. 2, 2015 and Korean Patent Application No. 10-2016-0111368, filed on Aug. 31, 2016, and all the contents disclosed in the literatures of the corresponding Korea patent applications are included as a part of the present specification.
- The present invention relates to a high internal phase water-in-oil type cosmetic composition, characterized by stabilizing pigments or dyes, which shows colors, in the internal phase part of the high internal phase water-in-oil type cosmetic composition and thus representing the colors of the internal phase when using the product, wherein the high internal phase water-in-oil type cosmetic composition can be used in the manufacture of cosmetic compositions with aesthetic and functional effects and in other similar applications.
- Dry skin is prone to wrinkles and vulnerable to aging. Accordingly, various forms of cosmetic compositions that can supply skin with moisture are available on the market. In particular, recently, a cosmetic product of the high internal phase water-in-oil type emulsion formulation which provides a visual effect such as water droplets bursting out upon application to the skin has been launched to provide a wider range of satisfaction. The high internal phase water-in-oil type emulsion formulation is prepared by significantly increasing the content of the aqueous phase which is the internal phase of the composition particles. In the case of such formulations, when the external stimulus, such as hand rubbing force is applied, the internal phases burst out and coalesce in the form of a water droplet, which is sometimes referred to as the ‘water bursting emulsion’ because it appears as if the water bursts out and forms a water droplet. This type of emulsion is attracting attention as a new type of moisturizing cosmetics that add fun and psychological satisfaction to product use since the water-containing state can be visually confirmed.
- However, the internal phase that bursts out from the conventional high internal phase water-in-oil type emulsion formulation is transparent color, and thus there are considerable limitations in producing various effects other than providing a sense of water. For example, there is a limitation to the applications in the case of expressing the feeling of nourishment in addition to the feeling of moisture or in the case of expressing the characteristics of various functional natural substances contained in the composition and so on by utilizing the characteristics of the internal phase that bursts out during use. Therefore, it is necessary to develop a further improved type of high internal phase water-in-oil type emulsion.
- Therefore, the inventors of the present invention have noted that when imparting colors to the internal phase of the emulsion formulation, various functional effects as well as aesthetic effects can be combined, and thus have completed the present invention through long research and efforts.

The water-in-oil type cosmetic composition is also called ‘water bursting’ formulation because it looks by the naked eye as if the water bursts out and forms water droplets, which is a formulation that can enhance the user's psychological and aesthetic satisfaction.
- The present invention can lead to more various characteristics and effectively highlight the function and purpose of each cosmetic composition by stabilizing the color-exhibiting pigments or dyes in the internal phase of the high internal phase water-in-oil type cosmetic composition.
- Among the above color-exhibiting materials, the dye can be freely used in all compositions, while the pigments are difficult to stand alone in a stabilized state in the internal phase and can cause separation of formulations during and after the manufacturing process. Therefore, even when these pigments are included, the present invention provides the combination and content of the most preferred composition to enable the production of a stable cosmetic composition
- However, it is not intended to limit the cosmetic composition of the present invention to only a specific range, and the cosmetic composition of the specific range should be understood as one implementation means for carrying out the present invention more broadly.
- Hereinafter, the present invention will be described in more detail.
- However, it is to be understood that the following description merely illustrates the most representative embodiments in order to facilitate understanding of the present invention and thus the scope of the present invention is not limited to the above embodiments, and that the present invention covers all of the equivalent scope of the following description.
- The cosmetic composition of the present invention having a color in the internal phase is prepared by the steps comprising preparing and warming an aqueous phase base and an oil phase base; preparing a water-in-oil (W/O) type emulsion by mixing and emulsifying the aqueous phase and the oil phase base; and re-warming for the surface filling of the water-in-oil type emulsion.
- In order to prepare the cosmetic composition of the present invention, first, the color-exhibiting pigments or dyes must be stabilized in the aqueous phase, which is the internal phase, in the mixing and emulsifying step, secondly, the emulsified emulsification particles should be formed stably, third, the stability should be maintained without separation of the formulation even at the re-warming step, and fourth, the final surface filling state should be uniform and flat. In particular, the colors are often not realized in the internal phase depending on other component substances contained even though it contains the pearls, color-exhibiting pigments or dyes. However, the present invention proposes a combination and content of component materials, which can stably maintain the pigments in the internal phase, while simultaneously satisfying the above-mentioned requirements.
- Specifically, the cosmetic composition of the present invention can satisfy the above-mentioned characteristics required in the production step by including the pearls and the thickener at the time of preparing the aqueous phase base, including a certain type of emulsifier and dispersant at the time of preparing the oil phase base and also limiting the type and blending ratio of the oil constituting the oil phase base.
- Hereinafter, each of the core components used in the production of the present invention will be described in more detail.
- Color-Exhibiting Pigment and Dye
- The present invention is based on adding color-exhibiting pigments or dyes and stabilizing it at the time of preparing the aqueous phase base, in order to embody the colors in the internal phase which forms water droplets when using high internal phase water-in-oil type cosmetic composition. The term ‘pigment’ as used in the present specification refers to a color as an inorganic substance, and ‘dye’ means a color-exhibiting material as organic substance.
- The pigments may be at least one of pearl particles and aqueous phase dispersion pigments.
- The pearl particles are preferably platelet powders such as mica, synthetic mica, alumina, borosilicate, boron nitride powder, talc, or sericite, and it is more preferable to coat the surface thereof with one or a mixture of two or more selected from the group consisting of titanium dioxide, tin oxide and iron oxide. The coating ratio is 2 to 60 wt. % based on the total weight of the pearl particles. In addition, it is preferable that the pearls used in the present invention are a fine interference pearl. The fine interference pearl is white in appearance color. However, since it increases the reflected light on the skin and has a unique interference color, it can show a bright and unique color. The size of the fine interference pearl particles is preferably 6-15 μm in diameter, more preferably 7.19 μm in diameter on average. If the size of the pearl particles is larger than the above range, it is difficult to entrap the particles in the emulsification particle. If the size of the pearl particles is smaller than the above range, the stability of the formulation may deteriorate due to the action at the interface. In other words, since the average particle size of the pearl particles affects the stability of the formulation, excessively large or small pearl particles are not uniformly present in the aqueous phase base and can be demarcated or can act on the interface and thus may degrade the stability of the emulsion.
- Conventionally, in contrast to other pigments or dyes, when using particularly the above-mentioned pearl-containing type pigments, there is a difficult limitation to independently stabilize these pigments in the internal phase. This is because titanium dioxide coated on the surface of pearl particles has generally a great tendency to be attracted to the oil phase which is external phase rather than the internal phase when emulsion is formed. However, the present invention can prevent this phenomenon and more stably disperse the pearl pigments in the internal phase by limiting the specific combination and content of the composition.
- Meanwhile, the term ‘aqueous phase dispersion pigment’ as used in the present specification refers to a powder formed by coating an inorganic material with hydrophilic particles. Although the pearl particles are not necessarily excluded from the range of the inorganic substance, it is usually more effective to use the form of utilizing pearl particles than that according to the foregoing, and it is preferable to use other inorganic materials in addition to pearls as the inorganic substance constituting the aqueous phase dispersion pigments. For example, the aqueous phase dispersion pigments of the present invention can be used in the form of titanium dioxide (TiO2) coated with at least one of alumina and silica. The content of the aqueous phase dispersion pigments is preferably 1 to 10% by weight, more preferably 1.5% by weight, relative to the total weight of the composition.
- Meanwhile, any dye that can be dispersed in the aqueous phase, such as an organic coloring, can be used as a dye without limitation.
- The color-exhibiting pigments or dyes can be selectively or simultaneously used, and the colors realized therefrom can be variously implemented according to the effect to be provided without limitation in any color. For example, a white pearl can be used to express moisturizing, nutritive, or whitening effect generated from milk or essence
- Emulsifier
- When the emulsion is emulsified, if the emulsification particles are formed small, the ‘water bursting’ phenomenon tends to be weakened. Therefore, in the present invention, in order to prevent the above problems and to stably contain the color pigments in the aqueous phase, emulsifiers are used to form large emulsification particles, and among these, certain kinds of emulsifiers are used in combination.
- As the emulsifier of the present invention, at least two selected from the group consisting of PEG-10 dimethicone; lauryl polyglyceryl-3 polydimethylsiloxyethyl dimethicone; lauryl PEG-9 polydimethylsiloxyethyl dimethicone; polyglyceryl-3 polydimethylsiloxyethyl dimethicone; caprylyl methicone (and) PEG-12 dimethicone/PPG-20 crosspolymer; dimethicone/PEG-10/15 crosspolymer; dimethicone/polyglycerin-3 crosspolymer; cetyl PEG.PPG-10/1 dimethicone; cetyl dimethicone copolyol; and dimethicone/vinyl dimethicone crosspolymer can be used. Dimethicone/PEG-10/15 crosspolymer, dimethicone/polyglycerin-3 crosspolymer, and cetyl PEG.PPG-10/1 dimethicone can be preferably used.
- The content of the emulsifiers is, but is not limited thereto, preferably 0.1 to 3 wt. % relative to the total weight of the composition.
- Dispersant
- On the other hand, although the pearls may be stabilized in the aqueous phase by the above-mentioned method, since large emulsification particles formed degrade the stability of the formulation or the pigments contained in the aqueous phase affects the stability of the interface, it is easy to cause a problem that the composition is separated during the process. In fact, there arises a problem that the formulation is easily separated during re-warming for filling the composition.
- For this purpose, in the case of the present invention, a certain kind of dispersant is added to the oil phase base, and the desired emulsifying retention force and the fluidity of the formulation are supplemented from the dispersant. However, not all dispersants contribute to emulsification. As a dispersant having an emulsifying power suitable for the present invention, two or more selected from polyhydroxy stearic acid, acrylates/ethylhexyl acrylate/dimethicone methacrylate copolymer, and vinylpyrrolidone/hexadecene copolymer can be used, and preferably, polyhydroxy stearic acid and acrylate/ethylhexyl acrylate/Dimethicone methacrylate copolymer can be used.
- The content of the dispersant is, but is not limited thereto, preferably 1 to 3 wt. % relative to the total weight of the composition.
- Thickener
- The thickener can be added to the aqueous phase base to adjunctively prevent the pearls contained in the aqueous phase, which is the internal phase, from being attracted to the oil phase which is the external phase.
- When the thickness of the interior increases by adding the thickener, it is also possible that the degree to which the pearls are attracted to the oil phase decreases, and a relatively large amount of pearls are contained compared to the conventional art.
- There are no particular restrictions on the type of thickener, but preferably at least one selected from the group consisting of xanthan gum, carbomer, hydroxypropyl starch phosphate, sodium magnesium silicate, hydroxyethyl cellulose, and hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer can be used, and the content thereof is preferably 0.01 to 0.5% by weight relative to the total weight of the composition.
- Film Former
- A film former can be added to give a feeling of close contact on the skin and enhance the sustainability of the makeup.
- MQ or T resins such as trimethylsiloxysilicate and polypropyl silsesquioxane, which are commonly used in makeup products, increases the pigment dispersibility in the formulation and disperses color-implementing particles present in the aqueous phase into the oil part. In the case of the present invention, a film former including hydrogenated polycyclopentadiene is used to enhance the adhesion and sustainability without affecting water bursting color.
- Combination of Oils
- If the final surface filling state is poor, the commercial value of the product is lowered. Therefore, the cosmetic composition of the present invention limits the combination of component materials to ensure an excellent degree of filling.
- The degree of filling is affected by the type and blending ratio of oils contained in the oil phase component, and the content of the dispersant which varies depending on the type and blending ratio. Specifically, the oils constituting the oil phase component of the present invention include silicone oil and ester oil, and the higher the blending weight ratio of ester oil to silicone oil, the better the degree of surface filling. This is because as the ester oil compared to silicone oil increases, the size of the emulsification particles increases and thus the high temperature fluidity increases, and as the high temperature fluidity increases, the degree of filling of the formulation becomes better.
- In the case of the present invention, when the blending weight ratio of ester oil to silicone oil is 1:0.2 or more, the desired degree of surface filling is obtained.
- Taking the above description into consideration, in a preferred embodiment of the present invention, a high internal phase water-in-oil type cosmetic composition, characterized by including each of silicone oil and ester oil in an amount of 3 to 7% by weight as an oil phase component, relative to the total weight of the composition, including each of dimethicone/PEG-10/15 crosspolymer, dimethicone/polyglycerin-3 crosspolymer and cetyl PEG.PPG-10/1 dimethicone in an amount of 0.1 to 3% by weight as an emulsifier, relative to the total weight of the composition, including each of polyhydroxy stearic acid and acrylates/ethylhexyl acrylate/dimethicone methacrylate copolymer in an amount of 1 to 3% by weight as a dispersant, relative to the total weight of the composition, including at least one selected from the group consisting of color-exhibiting pigment sand dyes in an amount of 1 to 2% by weight as an aqueous phase component, relative to the total weight of the composition, including hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer in an amount of 0.01 to 0.5% by weight as a thickener, relative to the total weight of the composition, and including hydrogenated polycyclopentadiene in an amount of 0.1 to 5% by weight as a film former, relative to the total weight of the composition, can be prepared.
- In addition to the above-mentioned materials, subsidiary component materials may be further contained as long as the effects of the present invention are not impaired.
- The water-in-oil type cosmetic composition of the present invention can be any emulsion formulation, but is particularly effective when it is prepared into pact, foundation, cream and the like.
- Hereinafter, experimental examples will be described in order to facilitate understanding of the present invention. However, the following experimental examples are only examples of the effects of the present invention, and the scope and effect of the present invention are not limited thereto.
- Hereinafter, Example 1 of the present invention and Comparative Examples 1 and 2 will be described. Experimental Examples 1 to 5 relating to the effects of the present invention are also described. The following Example 1 and Comparative Example 1 or 2 were used for the experiment.

- Referring to
FIG. 1 , (a) the left side is a formulation having the conventional transparent internal phase prepared according to Comparative Example 1, (b) the right side is a formulation, in which the colors are implemented in the internal phase, as prepared according to Example 1, and (b) it is possible to confirm the internal phases from the right figure, which are burst out in the form of white water droplets. - In the present invention, in order to impart colors to the internal phase, pearls or aqueous phase pigments are included in the aqueous phase, but according to this, the color implementation depends on the combination of other component materials. In Experimental Example 2, this fact and a combination of components suitable for the present invention were confirmed together by comparing and observing the form of the formulations according to the prescription,
-
FIG. 2 is one of the observation results of Experimental Example 2 - Referring to
FIG. 2 , (a) the left side is a formulation prepared according to Comparative Example 2 above, (b) the right side is a formulation prepared according to Example 1 above, and (a) and (b) formulations all contain pearls, it can be confirmed that there is an effect that the colors are implemented only in the right formulation. - It can be seen from Experimental Example 2 that the key element to implementing the present invention lies in the optimal combination of emulsifier, dispersant, thickener and preservative.
- The addition of a dispersant is essential in the present invention, compared with the formulation of the transparent internal phase.
- In Experimental Example 3, the addition effect of the dispersant was confirmed.
-
FIG. 3 relates to a formulation prepared by omitting the dispersant in the formulation of Example 1 above, and shows the states in which the separation of the formulation has occurred in the re-warming step during the process. - In Experimental Example 4, the correlation between the combination of oils in the oil phase component and the degree of surface filling of the composition, and optimal combination of oils to have the desired degree of surface filling were confirmed.
- Referring to
FIG. 4 , it can be confirmed that the degree of surface filling can be different by including silicone oil and ester oil as the oil component constituting the oil phase while controlling the weight ratio of the two oils. InFIG. 4 , the degree of surface filling is shown (a) when containing 13% of silicone oil and 1.5% of ester oil on the left side, (b) when containing 13% of the silicone oil and 2.56% of the ester oil on the middle side, and (c) when containing 8% of silicone oil and 5.56% of ester oil on the right side. It can be seen that the higher the ratio of ester oil to silicone oil, i.e., the more right-side the formulations, the better the degree of surface filling. - On the other hand, the degree of surface filling is determined depending on the degree of flow of the cosmetic composition at high temperatures. In addition, the high temperature fluidity increases with increasing particle size of the composition.
- In this regard, further experiments were conducted to confirm whether the above combination of silicone oil and ester oil affects the high temperature fluidity of the composition.
-
FIG. 5 shows the result of observing the particle size of emulsion containing silicone oil or ester oil with a microscope (Eclipse 80i, Nikon Instruments Korea, ×100). InFIG. 5 , (a) the left side is a general formulation, (b) the middle side is a formulation containing only silicone oil, and (c) the right is a formulation containing only ester oil. The general formulation refers to a formulation containing 1:1 of ester oil to silicone oil. - Referring to the result of the above observation, it can be seen that the formulation containing only silicone oil do not show a significant difference in particle size compared to the general formulation, but the particle size of the formulation containing only the ester oil is very large. That is, it can be seen that the higher the content of the ester oil, the larger the particle size of the composition, thereby improving the high-temperature flowability and ultimately improving the degree of surface filling.
- In the present Experimental Example 5, in order to investigate the effect of particle size of pearl particles on formulation stability and feeling of color, the average particle size of the composition comprising different pearl particles is shown in Table 4 below.
-
TABLE 4 Average particle size 5 μm 8 μm 16 μm 20 μm Characteristics Formulation Color Formulation No color separated separated - As shown in table 4, it can be confirmed that if the average particle size of pearl particles is 5 μm and 16 μm, the stability of the formulation deteriorates, and if the average particle size is 20 μm, the colors did not appear. Therefore, it can be seen that the average particle size of the pearl particles is suitably between 6 and 15 μm.
